abarbarian Posted December 13, 2020 Posted December 13, 2020 (edited) Found out that gnome-disk-utility has a component called gnome-disks which shows read and writes. You have to unmount the disk to get write data though. I stopped the test on the Samsung F3 hd and the SanDisk usb as they were taking too long, they were there just for fun anyway. Interesting to see the difference in the 860 EVO and the Crucial ssd. On arch there is a package, http:// https://www.archlinux.org/packages/extra/x86_64/gnome-disk-utility/ once installed you can run gnome-disks from the terminal. As we all have different ssd's it would be interesting to see the results for other drives. Edited December 13, 2020 by abarbarian Quote
